Hi Swapnil
Thanks for the output, this is odd that admin disk_space is showing the stable queue almost full but admin who,sqt is not showing any transactions and you do not have a save interval configured?
If this stable queue is still full and if possible can you upload the complete RS log if it is not to big so we can take a look at it?
Also can you send output of admin disk_space as well.
If we do not see something obvious in the RS log you will need to open an incident with support for a more detailed look.
Regards
Terry
